PROBLEM TO BE SOLVED: To provide a vacuum heat insulation material which has high gas barrier properties and which can maintain heat insulation performance even in a place which is exposed to high humidity, and a laminate for vacuum heat insulation material used for the same.SOLUTION: A laminate for vacuum heat insulation material is used for a vacuum heat insulation material in which a heat insulation core material is coated by the laminate for vacuum heat insulation material, and in which the inside is brought into a vacuum state by degassing. In the laminate for vacuum heat insulation material, steam permeability of the laminate for vacuum heat insulation material is equal to or less than 0.1 g/mday, and the steam permeability after bending is equal to or less than 0.5 g/mday.SELECTED DRAWING: Figure 1 |
